Which statement about indirect pulp caps is false?

  1. Some leathery caries may be left in the preparation

  2. A liner is generally recommended in the excavation

  3. The operator should wait at least 6-8 weeks before re-entry

  4. Indirect pulp cap has a poorer prognosis than direct pulp caps

The correct answer is: Indirect pulp cap has a poorer prognosis than direct pulp caps

Indirect pulp capping is a procedure performed when there is reversible pulpitis that has reached close to the pulp but has not yet affected it. It involves leaving a thin layer of affected dentin to protect the pulp. It is a conservative approach to treating deep caries lesions. The statement that is false is option D. Indirect pulp capping generally has a better prognosis than direct pulp capping. Direct pulp capping involves placing a material directly onto an exposed pulp site to encourage healing and is performed when there is a small exposure of the pulp. In comparison, indirect pulp capping has a higher success rate as it involves placing a material over affected dentin, which is more conducive to a favorable outcome.
